An autonomous mobile cleaning robot includes a cavity along a bottom portion of the robot, and a drive configured to support the robot above a floor surface. The drive is configured to propel the robot along the floor surface. The robot further includes a first electrical terminal disposed in the cavity and connected to electrical circuitry of the robot, a battery assembly, and a dovetail joint. The battery assembly includes a battery housing, a battery contained within the battery housing, and a second electrical terminal mounted to the battery housing and configured to engage with the first electrical terminal. The dovetail joint includes a vertically extending projection portion and a vertically extending socket portion.

Disclosed are a robot cleaner and a maintenance device for the same. The robot cleaner includes a body, a traveling module for moving the body, a bottom portion disposed in front of the traveling module for sliding along a floor when the body is moved, and a collection portion disposed in front of the bottom portion, the collection portion having therein a space for collecting foreign matter on the floor. The maintenance device includes a suction port configured to be inserted into the collection portion and a suction channel for guiding the movement of the air suctioned through the suction port.

A surface cleaning apparatus, such as a fluid delivery or steam mop, comprises a handle assembly comprising a steam distributor and a foot assembly pivotally attached to the handle assembly and comprising a base housing. The foot assembly can be used in two positions, whereby opposing sides of a cleaning pad on the base housing can selectively engage a surface to be cleaned. The foot assembly is further swivelable relative to the steam distributor, such that fluid can be delivered to the surface to be cleaned in both of the two use positions.

A surface cleaning apparatus for cleaning a surface includes a recovery tank with a lower portion with a bottom wall that defines an opening and an extraction nozzle that is in fluid communication with the recovery tank. A motor/fan assembly is in fluid communication with the extraction nozzle and the recovery tank to generate a working airflow to transport debris-containing fluid including air and liquid from the extraction nozzle into the recovery tank. The surface cleaning apparatus also includes an air/liquid separator assembly that is selectively insertable into the recovery tank. The air/liquid separator assembly includes a riser tube with a liquid conduit integrally formed with an air conduit and a float assembly that is operably coupled with the air conduit. A coupling joins the air/liquid separator assembly with the recovery tank.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

The present disclosure provides a movable electric device. The movable electric device includes a movable device body and a contact detection electrode. The movable device body has an electric drive means. The contact detection electrode is mounted on the movable device body. When the contact detection electrode _contacts diffusible dirt, a resistance, capacitance or impedance of the contact detection electrode varies.

An automatically moving floor treatment appliance has an appliance housing, a drive, a detector for detecting surrounding area features, and a computer that transmits control commands to the drive, based on the surrounding area features detected by the detector. The detector has a plurality of inner and outer fall sensors arranged on an underside of the appliance housing, which detect a distance of the floor treatment appliance from the surface. The computer controls the drive to change a movement of the floor treatment appliance when the distance detected by the fall sensor is greater than a threshold value defining a slope. The fall sensors are interconnected in an evaluation circuit of the detection means so that the detection signals of the totality of inner fall sensors can be evaluated independently of the detection signals of the totality of outer fall sensors.

An automatic cleaning device control method, an automatic cleaning device control apparatus, a computer-readable storage medium, and an electronic device are disclosed. The control method comprises: when an automatic cleaning device performs cleaning in a first surface medium area, in response to a surface medium sensor triggering a surface medium change signal, determining whether the automatic cleaning device is located in a second surface medium area; and in response to determining that the automatic cleaning device is located in the second surface medium area, according to a map of the second surface medium area and the current position of the automatic cleaning device, controlling the automatic cleaning device to deviate from the second surface medium area in a direction perpendicular to an edge of the second surface medium area.

A cleaning apparatus includes a device body; a bumper, connected to the device body and comprising a bumper opening, provided with a photography opening and an illuminator opening; a camera, oriented outside of the device body through the photography opening, configured to pick up an image of the environment to perform functions of object recognition; and an illuminator, oriented outside of the device body through the illuminator opening, configured to emit light to illuminate at least part of a recognition area of the camera.
